Hello Khan, Abstract Method Abstract Method resides in abstract class and it has no body. Abstract Method must be overridden in child child class. Virtual Method Virtual Method can reside in abstract and non abstract class. It is not necessary to override virtual method in derived but it can be. Virtual method can have body....Override by "override keyword"..... An abstract function can have no functionality. You're basically saying, any child class MUST give their own version of this method, however it's too general to even try to implement in the parent class. A virtual function , is basically saying look, here's the functionality that may or may not be good enough for the child class. So if it is good enough, use this method, if not, then override me, and provide your own functionality.
